St. Lucie County Sheriff Mascara announces arrest of high school teacher for sexual activity with a minor

St. Lucie County Sheriff's investigators have arrested a 35-year-old high school teacher for sexual activity with minors, according to Sheriff Ken J. Mascara.

"Friday night, we arrested Dominic L. Madison, a teacher at Treasure Coast High School," Sheriff Mascara said. "He faces 39 charges of sexual activity with minors and one count of using a child in a sexual performance. He is being held at the St. Lucie County jail under $1,535,000 bond."

Sheriff Mascara said the charges involve two female victims under the age of 18. "We believe there may be additional victims," said Sheriff Mascara. "I want to ask parents of Mr. Madison's female students to talk with their daughters. I encourage victims to contact Sheriff's detectives at 772-462-3230."

The "sexual performance" charge relates to a sexual encounter recorded by Madison and stored on one of his computers, Sheriff Mascara said. Detectives seized several of Madison's computers and storage devices, which detectives are examining for additional evidence.

Detectives also arrested Madison's girlfriend Friday night. Janifer Thomas, 35, is charged with being an accessory after the fact and failure to notify law enforcement of knowledge of a suspect of child abuse. Early Saturday morning, she was released from the county jail after posting $18,750.

Madison's crimes were reported to law enforcement Thursday night, Sheriff Mascara said. "Detectives worked around the clock to gather evidence and prepare documentation for arrest warrants which were signed by Circuit Court Judge Lawrence Mirman. I would like to thank the members of the U.S. Marshals Service for their invaluable assistance in helping our detectives locate and arrest the suspects in St. Lucie County."

The investigation is continuing with the possibility of additional charges.
